TIRE.

To all 1.0720112. it may concern:

Be it known that I, IsAAo BRooMn, a citizen of the United States,residing at Trenton, in the county of Mercer and State of New Jersey,have invented certain new and useful Ii'nprovements in Tires, of whichthe following is a. specification.

The present invention relates to a resilient tire for use in connectionwith automobiles or other vehicles, and has particular reference to atire formed of a plurality of sections or blocks of elastic material,which are completely covered by a metallic armor.

An important object of this invention is to provide a tire of the abovementioned character which will possess a desired degree of elasticityand last a very long time.

A further object of this invention is to provide a metallic armor tocover the blocks of rubber or other elastic material, which armor isformed in a plurality of sections to be suitably flexible and isprovided with novel means to prevent the same from slipping withrelation to the blocks of rubber.

Other objects and advantages of the invention will be apparent duringthe course of the following description.

In the accompanying drawings forming a part of this specification and inwhich like numerals are employed to designate like parts throughout thesame, Figure l is a fragmentary side view of a wheel equipped with myimproved resilient tire, Fig. 2 is a cross-sctional view taken on line22 of Fig. 1, Fig. 3 is a perspective view of one of the metal holdingmembers employed to secure the block of rubber to the telly, and, Fig. 4is a similar view of a plate or section comprised in the armor.

,In the drawings wherein is illustrated a preferred embodiment of myinvention, the numeral 1 designates the felly of a wheel of any wellknown or preferred type.

My improved tire comprises a plurality of holding members 2 which areformed of iron or other suitable meta-l. Each of these holding membersis radially disposed with relation to the felly and comprises a T-shaped outer portion 3 that is rigidly attached to and preferably formedintegral with an inner U-shaped portion 4. This U-shaped inner portionis adapted to straddle the felly 1 and is rigidly connected therewith bymeans of bolts 5 or the like. 7 e head of the outer T-shaped portion 3is Specification of Letters Patent.

provided at its ends with outwardly extending flanges fl.

The numeral 7 designates flanges or ribs which are formed upon the bodyportion of the T-shaped portion 3 at one end thereof, as shown.

The resilient tire comprises a plurality of compressible and expansiblesolid rubber having a desired degree of elasticity. Each of these blocksof rubber has a substantially T-sllapcd opening forn'ied theret-hroughfor receiving the T- shaped portion 3 of the holding member The block 8is also provided with suitable openings for receiving the outwardlyextending flanges ti. Surrounding, the blocks S is a suitably flexiblemetallic armor, which is formed of a plurality of curved plates orsections 9. Each of these plates or sections is preferably curved, asshown in Fig. 4-, with the free ends thereof bent outwardly, as shown at10. Rigidly connected with each armor plate 9 and preferably formedintegral therewith is an inwardly extending rib or flange 11, disposednear and spaced from one end of the plate. This rib serves to reinforceand stiffen the plate 9 and also engages between two of the blocks 8 toprevent the plate from creeping or slipping in relation to the block 8.

In assembling the parts of the tire, the holding member-.2 has itsT-shaped outer portion 3 inserted within the opening formed through theblock or section 8. The ribs or flanges 7 engage one end of the block toprevent said block from moving in that direction with relation to theholding member. The holding member .2 is then placed upon the folly sothat the U- shaped portion 4 thereof will straddle, the folly,subsequently to which it is attached to the telly by means of the boltsThe armor plate 9 is next placed on the block 8 thus assembled and theflange or rib 11v will engage one end of said block, whereby the armorplate is prevented from moving in one direction with relation to saidblock. The next. holding member 2 carrying its block is placed on thefolly and the. flange or rib 11 will occupy a position between theadjacent ends of the blocks 8. as shown.

It is to be understood that the form o." my invention herewith shown anddescribed is to be taken as a preferred example of the same and thatcertain changes in the shape,

sections or blocks 8, which are preferably formed of size, andarrangement of parts may be resorted to without departing from thespirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I claim The combination with thefelly of a wheel, of a plurality of elastic blocks arranged about thefelly, each elastic block having an enlarged head which is approximatelycylindrical and a reduced inner shank, means to securely attach theblocks to the telly, and a metallic armor surrounding the blocks andincluding a plurality of metallic plates which are approximatelycylindrical to correspond'to the curvature of said blocks and havingtheir free ends engaging the reduced shanks to prevent their lateraloeeaer spreading, each metallic plate being provided upon its innersurface with a relatively shallow rib extending substantially the entirelength of the metallic plate and adapted to be inserted for a shortdistance only between two adjacent elastic blocks whereby the metallicplate is prevent-e from creeping with relation to the blocks,

said metallic plate is suitably reinforced and stiffened, and the entirestructure possesses a desired degree of resiliency.

In testimony whereof I aflix my signature in presence of two Witnesses.

ISAAC BROOME.
